Laser hair removal damages individual hair follicles to inhibit future hair growth. Both men and women undergo laser hair removal procedures for various reasons, including excessive hair growth and hair in undesirable places, such as facial hair on women. Laser hair removal is effective for many people, though as with any medical procedure, it does carry some risks and concerns.
Skin Irritation
Pain and swelling at the hair removal site are common side effects following the procedure. These usually subside on their own after a short period. Your skin may scab or blister slightly following the procedure due to the laser irritating the first few layers of skin. Your doctor may prescribe topical antibiotics to combat blistering if it occurs. Mild steroid creams can help relieve pain and swelling, though many people are able to treat these side effects with ice packs and over-the-counter pain relievers. It is important to wear a strong sunscreen with an SPF of 30 following a laser hair removal treatment to avoid skin damage and irritation, advises the American Academy of Dermatology.
Infection
Although it is rare, some people may get an infection following the procedure. The risk of infection is increased if you develop blisters or severe skin irritation. Keeping your skin clean with a mild cleanser and following your doctor's post-procedure instructions carefully can help you minimize your risk of infection. If you experience severe pain, redness or swelling, notify your doctor as soon as possible. Fever is also a common sign of infection. Most infections following laser hair removal are not serious and can be treated successfully with antibiotics if you seek prompt medical attention.
Pigment Changes
Some people experience pigment changes following laser hair removal. These effects are usually temporary, though they can take several months to resolve, according to the American Academy of Dermatology. Skin lightening usually affects patients with darker skin, especially if the doctor uses an incorrect laser setting. Darkening of the skin is also possible, particularly in patients with lighter skin tones.
Results
Laser hair removal is most effective for people with light skin and dark hair, according to MayoClinic.com. It often takes several treatments to achieve the desired results. The American Academy of Dermatology advises patients to expect 10 to 25 percent of the hair to regrow with each treatment. You can have subsequent hair removal treatment sessions every four to eight weeks if you do not experience complications. You may require further treatments to maintain them, states MayoClinic.com. You also may need maintenance treatments as often as once every six to 12 months, states MayoClinic.com.
